以前的研究预击穿现象在非常纯的液体环己烷中已经表明，在一个点-平面电极组件和负极性的点，可以观察到一个规则的电流脉冲制度。这种脉冲制度，非常类似于在空气中发现的Trichel脉冲，对应于环己烷液相中的电子雪崩机制。实验和半经验研究表明，环己烷（N=5.57 × 10/sup 21/ cm/sup-3/）的液相放电与数密度仅为2.5 × 10/sup 21/ cm/sup-3/的气相放电相似。在丙烷中得到相同的结果。从已知的值的倍增系数α在气态丙烷和环己烷中，在液相中的α值估计根据电场。>
Previous studies of prebreakdown phenomena in very pure liquid cyclohexane have shown that, in a point-plane electrode assembly and for negative polarity of the point, a regular current pulse regime can be observed. This pulse regime, very similar to Trichel pulses found in air, corresponds to a mechanism of electron avalanche in the liquid phase of cyclohexane. Experimental and semiempirical investigations lead to the conclusion that the electrical discharge in the liquid phase of cyclohexane (N=5.57*10/sup 21/ cm/sup -3/) is similar to that in the vapor phase at a number density of only approximately 2.5*10/sup 21/ cm/sup -3/. The same results are obtained in propane. From known values of the multiplication coefficient alpha in gaseous propane and cyclohexane, values of alpha in the liquid phases are estimated according to the electric field. >
